Mathematical Reasoning

You don’t have to have a “math mind” to pass the GED® Math test -- you just need the right preparation.

Here's what you need to know:

  • You should be familiar with math concepts, measurements, equations, and applying math concepts to solve real-life problems.
  • You don’t have to memorize formulas and will be given a formula sheet in the test center as well as on the screen in the test.
  • Use the free Math Study Guide to start studying. It will help you understand the skills being tested. Log in to start using the study guide.
  • The GED Ready® practice test for Math can help you determine if you are ready to take the actual test. Log in to take the practice test.

Question Overview

This question requires you to order a set of fractions and decimals from smallest to largest. First, the numbers must all be converted to the same format--either all fractions or all decimals--then the resulting numbers are placed in order. (NOTE: On the GED® Mathematical Reasoning test, a calculator would not be available to you on this question.)

A list of numbers is shown

1⁄2, 0.6, 4⁄5, 1⁄8, 0.07

Which list shows the numbers arranged from smallest to largest?

Option A is correct. This response is the result of either converting the decimals to fractions, or the fractions to decimals, then comparing the results, and placing the original numbers in the correct order.

Option B is incorrect. If you selected this response, you incorrectly compared the non-zero numbers in the decimals with the denominators in the fractions, before attempting to place them in numerical order.

Option C is incorrect. If you selected this response, you made a mistake with the 0.07, incorrectly reading it as 0.7, and placing it between 0.6 and 4⁄5.

Option D is incorrect. If you selected this response, you made a calculation error in converting, obtaining an answer of 0.4 and placing it between 1⁄8 and 1⁄2.
